DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The technical solution of the present disclosure will be describedclearly and completely below with reference to the embodiments shown infigures. Obviously, the described embodiments are only some of theembodiments of the present disclosure, rather than all of theembodiments. Based on the description of the present disclosure, allother embodiments obtained by a person of ordinary skill in the artwithout creative work shall fall within the protection scope of thepresent disclosure.

The aerosol generating device of the embodiment of the presentdisclosure is an aerosol generating device that uses an air pump tosupply e-liquid. The aerosol generating device may include: atomizer,absorbing member, heating member and other components. The absorbingmember may be cotton, fiber, absorbent ceramic, or the like. The heatingmember may be a heating wire, a heating sheet, or the like. The inventorof the present disclosure unexpectedly found in the research work thatwithin a certain period of time after lighting the cigarette, under thecondition that the heating member is different, the amount of e-liquidis different, and the initial temperature of the heating member isdifferent, the real-time temperature change value of the heating memberhas a certain relationship with the remaining e-liquid in the atomizer.Specifically, as shown in FIG. 1 , the amount of e-liquid in series 1 to7 gradually decreases, and as the amount of e-liquid decreases, thereal-time temperature change value of the heating member will becomehigher and higher. Similarly, as shown in FIG. 2 , the amount ofe-liquid in series 1 to 2 gradually decreases, and as the amount ofe-liquid decreases, the real-time temperature change value of theheating member will become higher and higher. In addition, the initialtemperature of the heating member in FIG. 1 is low, and the real-timetemperature change value of the heating member is about 60˜130° C.; theinitial temperature of the heating member in FIG. 2 is high, and thereal-time temperature change value of the heating member is about 50˜70°C.; therefore, when the initial temperature is low, the real-timetemperature change value is larger; when the initial temperature ishigh, the real-time temperature change value is small. Based on theaccidental discovery, the embodiment of the invention provides ae-liquid supply method, using the relation of temperature and e-liquidamount to supply specific amount of e-liquid. It should be understoodthat the e-liquid of the embodiment of the present invention is anaerosol forming matrix; the e-liquid is not a certain tobacco product ortobacco product.

Specifically, as shown in FIG. 3 , the e-liquid supply method accordingto the embodiment of the present disclosure includes the followingsteps:

Step S110 obtaining the real-time temperature of the heating member ofthe aerosol generating device every first preset period after lighting acigarette.

The first preset period should not be too long, otherwise the real-timetemperature of the heating member cannot be more accurately reflected.In a preferred embodiment of the present disclosure, the first presetperiod is 10 ms, the real-time temperature of the heating member isobtained every 10 ms, which can not only reflect the real-timetemperature but also improve the efficiency.

Because the resistance value of the heating member having a specificmaterial will change with the change of temperature, such as SS316heating member. Based on this principle, the real-time temperature ofthe heating member can be determined by detecting the resistance valueof the heating member. The inventor of the present disclosure hasfurther discovered unexpectedly in the research work in the secondpreset period after lighting the cigarette, under the conditions of thegiven capacity of the atomizer and the material of the heating member;there is a certain corresponding relationship between the number oftimes that the real-time temperature change value of the heating memberis not less than the temperature change threshold value and the liquidsupply amount of the e-liquid.

Based on the above principles, in a preferred embodiment of the presentdisclosure, a heating member whose resistance value changes with thetemperature of the heating member is used. Based on this heating member,as shown in FIG. 4 , step S110 specifically includes the followingprocesses:

Step S111 detecting and obtaining the initial resistance value of theheating member after the aerosol generating device is inserted into theatomizer.

Wherein, the initial resistance value of the heating member isrepresented by R1 The initial resistance value can be detected by theexisting detection device.

Step S112: detecting and obtaining the real-time resistance value of theheating member every first preset period, after lighting the cigarette.

Wherein, the real-time resistance value of the heating member isrepresented by R2, the real-time resistance value can be detected by theexisting detection device. For example, the real-time resistance valueis detected every 10 ms after lighting the cigarette.

Step S113: calculating the real-time temperature of the heating memberaccording to

$T = {\frac{\left( {R_{2} - {R_{1} \times 10}} \right) \times 1000}{R_{1} \times {TCR}} + {20.}}$

Among them, TCR represents resistance temperature coefficient of theheating member. In a preferred embodiment of the present disclosure,using this formula, by detecting the resistance of the heating memberwhich is relatively easy and accurate to detect. the real-timetemperature of the heating member can be calculated conveniently andaccurately, so that the e-liquid can be supplied safely and reliablybased on the real-time temperature of the heating member.

Step S120: if at least one real-time temperature change value of theheating member within a second preset period after lighting thecigarette is not less than the temperature change threshold, supplyingthe e-liquid for the first time.

After lighting the cigarette, the current is turned on, and thereal-time temperature of the heating member will change. Among them, thereal-time temperature of the heating member obtained for the first timeis the initial temperature. That is, the real-time temperaturecorresponding to the first preset period after lighting the cigarette isthe initial temperature. Therefore, the real-time temperature changevalue is the difference between each real-time temperature and theinitial temperature. It should also be understood that since thereal-time temperature is acquired every first preset period, thereal-time temperature change value is also acquired every first presetperiod. The time length of the second preset period is greater than thetime length of the first preset period. Since the e-liquid is notsupplied within the second preset period, the second preset periodshould not be too long, otherwise dry burning will occur. In a preferredembodiment of the present disclosure, the second preset period is 100ms. The temperature change threshold can be determined according to theinitial temperature of the heating member and the material of theheating member. For example, the real-time temperature of the heatingmember in the first 10 ms after lighting the cigarette is the initialtemperature. The difference between the real-time temperature and theinitial temperature for each 10 ms after the first 10 ms within 100 msis the real-time temperature change value.

If the real-time temperature change values of the heating member withinthe second preset period after lighting the cigarette are all smallerthan the temperature change threshold, it indicates that the amount ofe-liquid remaining in the atomizer of the aerosol generating device issufficient to make the absorbing member of the aerosol generating devicewetting, therefore, it is not necessary to supply new e-liquid.

If at least one real-time temperature change value of the heating memberwithin the second preset period after lighting the cigarette is not lessthan the temperature change threshold, it indicates that the amount ofe-liquid remaining in the atomizer of the aerosol generating device isnot enough to wet the absorbing member of the aerosol generating device.Therefore, a first supply of e-liquid is required so that the amount ofe-liquid in the atomizer is sufficient to wet the absorbing member ofthe aerosol generating device.

Therefore, with this step, in the initial period of time after lightingthe cigarette, when the amount of cigarette e-liquid is insufficient,the cigarette e-liquid can be supplied for the first time to make thee-liquid absorbing member just wet, so as to avoid the phenomenon of dryburning and sticky smell.

In a preferred embodiment of the present disclosure, supplying thee-liquid for the first time is performed according to the correspondingrelationship between the number of times that the real-time temperaturechange value of the heating member is not less than the temperaturechange threshold value and the liquid supply amount of the e-liquidwithin the second preset period after the cigarette is lit.Specifically, as shown in FIG. 5 , step S120 includes the followingprocesses:

Step S121: obtaining the number of times that the real-time temperaturechange value of the heating member is not less than the temperaturechange threshold within the second preset period after lighting thecigarette.

In a preferred embodiment of the present disclosure, as shown in FIG. 6, step S121 can be implemented through the following process:

Step S1211: calculating the difference between each real-timetemperature of the heating member within the second preset period andthe real-time temperature of the heating member acquired for the firsttime, to obtain the real-time temperature change value of the heatingmember.

As mentioned above, the real-time temperature of the heating memberacquired for the first time is the initial temperature.

Step S1212: determining the temperature change threshold according tothe real-time temperature of the heating member obtained for the firsttime and the material of the heating member obtained for the first time.

Specifically, the correspondence between the real-time temperatureobtained for the first time and the temperature change threshold can bedetermined through a large number of experiments in advance that underheating member having the specific material. Therefore, according to thecorresponding relationship, the temperature change threshold can bedetermined.

Step S1213: comparing the magnitude relationship between each real-timetemperature change value of the heating member and the temperaturechange threshold, to obtain the number of times that the real-timetemperature change value of the heating member is not less than thetemperature change threshold.

For example, the first preset period is 10 ms, and the second presetperiod is 100 ms. The real-time temperatures of the six experimentalgroups within 100 ms are shown in Table 1. If the temperature changethreshold is 115° C., the 6th group has a temperature not less than thetemperature change threshold, the number of times that the 6th group isnot less than the temperature change threshold is 2 times.

TABLE 1 Real-time temperature in the second preset period Real-timetemperature/° C. (The volume of e-liquid smoke gradually decreases fromleft to right) Time/ms 1 2 3 4 5 6 10 20 24 20 26 26 20 20 22 35 30 4085 103 30 35 44 38 56 90 110 40 42 63 87 92 100 115 50 51 67 90 96 105119 60 60 72 94 99 107 119 70 67 76 99 106 119 126 80 79 99 103 112 124130 90 81 100 103 112 124 140 100 88 101 108 115 137 135

In this step, through the above process, the number of times that thereal-time temperature change value of the heating member is not lessthan the temperature change threshold value can be obtained.

Step S122: according to a first preset relationship, suppling thee-liquid for the first time according to the liquid supply amount of thee-liquid corresponding to the number of times that the real-timetemperature change value of the heating member is not less than thetemperature change threshold within the second preset period afterlighting the cigarette.

Wherein, the first preset relationship is that under the constraints ofthe capacity of the atomizer of the aerosol generating device and thematerial of the heating member, the corresponding relationship betweenthe number of times that the real-time temperature change value of theheating member is not less than the temperature change threshold withinthe second preset period after lighting the cigarette and the liquidsupply amount of the e-liquid. The corresponding relationship satisfiesthe requirement of wetting the absorbing member of the aerosolgenerating device. The capacity of the atomizer is different, and thematerial of the heating member is different, which will affect thereal-time temperature, the temperature change threshold, the amount ofe-liquid that can be accommodated, etc. Therefore, it will affect theliquid supply amount of the e-liquid. The first preset relationship canbe determined in advance through a large number of experiments.Specifically, the corresponding relationship test will be performed inadvance according to the capacity of different atomizers and thematerials of different heating members to determine the liquid supplyamount of e-liquid required to just wet the absorbing member of theaerosol generating device. Generally, the more times the real-timetemperature change value is not less than the temperature changethreshold, the less the amount of e-liquid remaining in the atomizer.

The above-obtained first preset relationship may be represented by acurve, a table, a formula, or the like. The first preset relationshipmay be stored in the electronic cigarette chip, the cloud, a thirdparty, and the like.

Therefore, in a preferred embodiment of the present disclosure, in theinitial stage of cigarette lighting, according to the first presetrelationship, according to the liquid supply amount corresponding to thenumber of times that the real-time temperature change of the heatingmember is not less than the temperature change threshold within thesecond preset period after lighting the cigarette, an appropriate amountof e-liquid is supplied at one time, so that the absorbing member of theaerosol generating device is just wet, so as to avoid the phenomenon ofdry burning and sticky smell.

Step S130: after suppling the e-liquid for the first time, suppling thee-liquid in real time according to the liquid supply amount of thee-liquid corresponding to the real-time temperature of the heatingmember.

after supplying the e-liquid for the first time, along with theconsumption of e-liquid, it is necessary to supply e-liquid in real timeto avoid the phenomenon of dry burning and sticky smell caused by notsupplying e-liquid in time. Therefore, in this step, according to thereal-time temperature of the heating member, a corresponding amount ofe-liquid is supplied in real time. Specifically, the liquid supplyamount of the e-liquid corresponding to the real-time temperature of theheating member satisfies the requirement of maintaining a balancebetween the liquid supply amount of the e-liquid and the liquidconsumption amount of the e-liquid.

Specifically, step S130 can be implemented through the followingprocess:

according to the second preset relationship, after the e-liquid issupplied for the first time, the e-liquid is supplied in real timeaccording to the liquid supply amount of the e-liquid corresponding tothe real-time temperature of the heating member.

Wherein, the second preset relationship is that under the constraints ofthe capacity of the atomizer of the aerosol generating device and thematerial of the heating member, the corresponding relationship betweenthe real-time temperature of the heating member and the liquid supplyamount of the e-liquid, and the corresponding relationship satisfies therequirement of maintaining a balance between the liquid supply amount ofthe e-liquid and the liquid consumption amount of the e-liquid. Thecapacity of the atomizer is different, and the material of the heatingmember is different, which will affect the real-time temperature, theamount of e-liquid that can be accommodated, etc., therefore, it willaffect the liquid supply amount of the e-liquid. The second presetrelationship can be determined in advance through a large number ofexperiments. Specifically, according to the capacity of differentatomizers and the material of different heating members, thecorresponding relationship test will be carried out in advance todetermine the liquid supply amount of e-liquid that keeps the liquidsupply amount of e-liquid and the e-liquid consumption of e-liquid inbalance.

The above-obtained second preset relationship may be represented by acurve, a table, a formula, or the like. The second preset relationshipmay be stored in the electronic cigarette chip, the cloud, a thirdparty, and the like.

According to the second preset relationship, a corresponding amount ofe-liquid is supplied, so as to kept the liquid supply amount of thee-liquid and the liquid consumption amount of the e-liquid in balance,and avoid the phenomenon of dry burning and sticky smell.

To sum up, the e-liquid supply method according to the embodiment of thepresent disclosure, the e-liquid can be supplied safely and reliably. Inthe initial stage of cigarette lighting, an appropriate amount ofe-liquid is supplied at one time, so that the e-liquid absorbing memberis just wetted and the phenomenon of dry burning and sticky smell isavoided after the first supply of e-liquid, according to the liquidsupply amount of e-liquid corresponding to the real-time temperature ofthe heating member, an appropriate amount of e-liquid is supplied inreal time, so that the supply and consumption of e-liquid can bebalanced, avoid the phenomenon of oil frying or even oil spill due toexcessive e-liquid supply. It also avoids the phenomenon of dry burningand sticky smell due to insufficient e-liquid supply.
